Image Compression
The process of reducing image file size while attempting to preserve image quality, making files faster to load on web pages without (ideally) visible quality degradation.
What is Image Compression?
Image compression is critical for e-commerce page speed, which directly impacts SEO and conversion. Lossless compression (PNG, lossless WebP) reduces file size without any quality loss. Lossy compression (JPEG, lossy WebP) achieves much greater file size reduction at the cost of some quality degradation. For e-commerce, the goal is the smallest possible file size at which image quality remains indistinguishable from the original. Tools like TinyPNG, Squoosh, and ImageOptim automate this process.
E-Commerce Relevance
Product page load speed directly impacts bounce rate and conversion — compressed images that maintain visual quality are one of the most impactful technical optimizations.
